If the experimental data obeys neither equation, then it is likely that another mechanism is taking place and Ostwald ripening is not occurring. Although LSW theory and Ostwald ripening were intended for solids ripening in a fluid, Ostwald ripening is also observed in liquid-liquid systems, for example, in an oil-in-water emulsion ...
Evolution of random initial data with = and = (60/40 mix of the blue and red phases, respectively), demonstrating Ostwald ripening When one phase is significantly more abundant, the Cahn–Hilliard equation can show the phenomenon known as Ostwald ripening, where the minority phase forms spherical droplets, and the smaller droplets are absorbed ...
Manifest functions are the consequences that people see, observe or even expect. It is explicitly stated and understood by the participants in the relevant action. The manifest function of a rain dance, according to Merton in his 1957 Social Theory and Social Structure, is to produce rain, and this outcome is intended and desired by people participating in the ritual.
Social comparison theory – suggests that humans gain information about themselves, and make inferences that are relevant to self-esteem, by comparison to relevant others. Social exchange theory – is an economic social theory that assumes human relationships are based on rational choice and cost-benefit analyses. If one partner's costs begin ...
For example, if n were less than one, the power law predicts that the effective viscosity would decrease with increasing shear rate indefinitely, requiring a fluid with infinite viscosity at rest and zero viscosity as the shear rate approaches infinity, but a real fluid has both a minimum and a maximum effective viscosity that depend on the ...
Friedrich Wilhelm Ostwald (German: [ˈvɪlhɛlm ˈɔstˌvalt] ⓘ; 2 September [O.S. 21 August] 1853 – 4 April 1932) was a German chemist and philosopher.Ostwald is credited with being one of the founders of the field of physical chemistry, with Jacobus Henricus van 't Hoff, Walther Nernst and Svante Arrhenius.

Another notable example of this relation is Ostwald ripening, in which surface tension causes small precipitates to dissolve and larger ones to grow. Ostwald ripening is thought to occur in the formation of orthoclase megacrysts in granites as a consequence of subsolidus growth. See rock microstructure for more.
Ostwald's rule is not a universal law but a common tendency observed in nature. [ 3 ] This can be explained on the basis of irreversible thermodynamics, structural relationships, or a combined consideration of statistical thermodynamics and structural variation with temperature.
